The New Jersey shoreline that sea birds wandered during the last ice age is about 90 miles east of today's beaches, tens of meters beneath the sea floor. As the ice melted, sea level gradually rose and flooded the coastal ...

A plan to help the world's coastal regions protect themselves against killer weather like Superstorm Sandy is pitting a group of scientists against an array of environmentalists and politicians, who fear that it could harm ...

At a unique lab in Trondheim, Norway, Siemens researchers are examining how power network components behave when subjected to extreme water pressures. In 2020, such a system will begin supplying energy to large oil and natural ...

Around 55 million years ago, an abrupt global warming event triggered a highly corrosive deep-water current through the North Atlantic Ocean. The current's origin puzzled scientists for a decade, but an international team ...

Seabed

The seabed (also known as the seafloor, sea floor, or ocean floor) is the bottom of the ocean. At the bottom of the continental slope is the continental rise, which is caused by sediment cascading down the continental slope. The seabed has been explored by submersibles such as Alvin and, to some extent, scuba divers with special apparatuses. The process that continually adds new material to the ocean floor is seafloor spreading and the continental slope.
